In the evening of Sunday local time, a school-wide on-site avoidance order was issued through the campus alert system, official social media, etc., at the Public University of Dowson, Maryland State, in response to a shooting incident on the York Road section of the campus, requiring all school personnel to stay indoors, close doors and windows and stay away from windows immediately until an official release notice was issued. Several local media reports confirmed that the order was triggered by a shooting investigation along York Road, that the incident had not yet resulted in casualties within the campus, that the Baltimore County Police were investigating the shooting, that the school maintained real-time communication with the local police and that the security situation on the campus would be updated as soon as the risk assessment was completed.
According to public information reported by various media outlets, the timing of the incident dates back to Sunday evening, when the district police in Baltimore first received a warning of shooting in the York Road section and then quickly blocked the relevant section of the road for investigation. As York Road is the central backbone connecting the campus of the University of Towson with the city of Baltimore, the shooting occurred in areas only hundreds of metres from the campus boundary and in high-risk public areas around the campus. Upon receiving a risk notification from the local police, the University of Tutson police urgently launched a campus security response mechanism that night, after which an on-site avoidance order was issued to the school ' s teachers and students ' staff, requiring that all those present on the campus (including students, school teaching scientists, logistics staff, visitors to the school area, etc.) immediately cease all outside activities, leave the indoor space at their current location and avoid travelling to the York Road area and the surrounding area of the campus until they receive a notice of removal from the school.
In issuing the avoidance order, the official of the University of Tutson made it clear that the institution-wide avoidance measures were initiated on the basis of the precautionary principle, with the aim of avoiding the error of the school personnel into the surrounding dangerous areas and providing maximum security to the campus community. There is currently no information that the shooting took place inside the campus of Tuttson University and that there was no direct security threat to the school personnel. After the incident, the district police in Baltimore also notified through public channels of the shooting in York Road, but, as of the time of the issuance of the media reports, the police had not published details of the shooting, including whether there had been any casualties, whether the suspects were at large, the cause of the incident, or the time of its release. For its part, Tutson University indicated that the school security team would continue to keep pace with the Baltimore County Police and, as soon as the surrounding risks were removed, would issue notice of the release order through channels such as the campus alert system, the network of school officials and official social media, as well as timely publication of incident-related information in response to community concerns.
This in situ avoidance order directly affected nearly 20,000 teachers and students at the University of Dowson, as well as all visitors who were active on the campus at the time of the incident. In the case of students in schools, the original travel, shopping, community activities are all disrupted and need to be kept in dormitories to avoid going out. Some dormitories will require students to remain in indoor public areas or in private rooms and not to move at will on campus; in the case of teachers and students with curricula on that day, the faculties have informed them, via mail, clusters, etc., that the courses have been temporarily cancelled or adjusted online, and that the experimental or practical courses have been suspended; in the case of logistics and administrative staff working in schools, the security arrangements for the schools have been temporarily cancelled or extended; in the case of public services for students and teachers, such as loaning, catering services may be temporarily curtailed or suspended; in the case of students who were visiting the school areas at that time, such as visitors to campus sports competitions, company personnel coming to the school recruitment fairs, visitors, etc., there is a need to be a follow-up to the activities planned for campus events, sports events have been temporarily cancelled or extended; and in the case of sports competitions at the Tutson University's many high schools, such as those scheduled in the recent school competitions competitions In addition, since the University of Dowson is one of the largest public institutions of higher education in Maryland and is an important anchor in the Baltimore region, the security response has also affected neighbouring enterprises and institutions that cooperate with schools, and there has been a temporary suspension of the in-school cooperation activities, job fairs, etc.
For teachers and students at the University of Dowson and visitors, it is now necessary to follow closely all notices issued by the University, not to leave the indoor area without permission, and not to go to the risk areas along the York Road and around the campus, and to contact the police department of the University of Dowson for assistance if urgent needs arise. For out-of-school staff planning to visit the University of Towson in the near future, it is recommended that the school ' s counterpart be contacted in advance to confirm the safety of the campus and the organization of activities and avoid unnecessary travel. The district police in Baltimore will continuously update the progress of investigations into the shooting, and the University of Tutson will issue a follow-up notice as soon as the risk is removed. The public will have access to the latest information through the official channels of the school and will not need to rely on rumours from unofficial channels. There is currently no information on the long-term relevance of the incident to the regular teaching and research activities of the University of Dowson, which assesses the need to adjust security measures around the campus after the incident has been disposed of, and subsequent adjustments are publicized in advance through official channels.
